The very concept of swear words is daft, in my opinion. The language used on TV just proves my point really. Can't say the f word? It's OK, we'll say frell or frak instead! Different word, same meaning, yet it doesn't get the censors in a tizzy!
Regarding all this rubbish about getting animalistic, I'll just say it's far more fun to get animalistic than to be a prude
